Therefore, embodiments can take the form of a completely hardware embodiment, a completely software embodiment (including firmware, resident software, microcode, etc.), or an embodiment combining software and hardware aspects, which are generally referred to herein as “circuit,” “module,” or “system.” Furthermore, embodiments can take the form of a program product embodied in one or more computer-readable storage devices stored in machine-readable code, computer-readable code, and / or program code, hereinafter referred to as code. The storage device can be tangible, non-transitory, and / or non-transferable. The storage device may not embody signals. In one embodiment, the storage device only employs signals for accessing the code.

[0030] Certain functional units described in this specification may be labeled as modules to more specifically emphasize their implementation independence. For example, a module may be implemented as hardware circuitry comprising custom-designed very large-scale integration (“VLSI”) circuitry or gate arrays, off-the-shelf semiconductors such as logic chips, transistors, or other discrete components. Modules may also be implemented in programmable hardware devices such as field-programmable gate arrays, programmable array logic, programmable logic devices, etc.

[0031] Modules can also be implemented in code and / or software to be executed by various types of processors. An identified code module may, for example, comprise one or more physical or logical blocks of executable code, which may be organized, for example, as objects, procedures, or functions. However, the executable files of an identified module do not need to be physically located together, but may include entirely different instructions stored in different locations, which, when logically connected together, constitute the module and achieve the module's purpose.

[0032] In practice, a code module can be a single instruction or many instructions, and can even be distributed across several different code segments, different programs, and span multiple memory devices. Similarly, in this document, operational data can be identified and visualized within a module, and can be represented in any suitable form and organized within any suitable type of data structure. Operational data can be collected as a single dataset or can be distributed across different locations, including different computer-readable storage devices. Where the module or part of a module is implemented in software, the software portion is stored on one or more computer-readable storage devices.

[0033] Any combination of one or more computer-readable media may be used. A computer-readable medium may be a computer-readable storage medium. A computer-readable storage medium may be a storage device for storing code. A storage device may be, for example, but not limited to, electronic, magnetic, optical, electromagnetic, infrared, holographic, micromechanical, or semiconductor systems, apparatuses, or devices, or any suitable combination thereof.

[0034] More specific examples of storage devices (a non-exhaustive list) will include the following: electrical connections having one or more wires, portable computer disks, hard disks, random access memory (“RAM”), read-only memory (“ROM”), erasable programmable read-only memory (“EPROM” or flash memory), portable compact optical disc read-only memory (“CD-ROM”), optical storage devices, magnetic storage devices, or any suitable combination of the foregoing. In the context of this document, a computer-readable storage medium can be any tangible medium capable of containing or storing programs for use by or in connection with an instruction execution system, apparatus, or device.

The code can be executed entirely on the user's computer, partially on the user's computer, as a standalone software package, partially on the user's computer and partially on a remote computer, or entirely on a remote computer or server. In the latter case, the remote computer can be connected to the user's computer via any type of network including a local area network ("LAN") or a wide area network ("WAN"), or can be connected to an external computer (e.g., via the Internet through an Internet service provider).

[0036] Throughout this specification, references to "an embodiment," "embodiment," or similar language mean that a particular feature, structure, or characteristic described in connection with that embodiment is included in at least one embodiment. Therefore, unless expressly stated otherwise, the phrases "in an embodiment," "in an embodiment," and similar language appearing throughout this specification may, but not necessarily all, refer to the same embodiment, but rather mean "one or more, but not all, embodiments." Unless expressly stated otherwise, the terms "comprising," "including," "having," and variations thereof mean "including, but not limited to,". Unless expressly stated otherwise, the list of items does not imply that any or all items are mutually exclusive. Unless expressly stated otherwise, the terms "a," "an," and "the" also mean "one or more".

Numerous specific details, such as examples of programming, software modules, user selection, network transactions, database queries, database structures, hardware modules, hardware circuits, hardware chips, etc., are provided in the following description to provide a thorough understanding of the embodiments. However, those skilled in the art will recognize that the embodiments can be practiced without one or more of these specific details, or using other methods, components, materials, etc. In other instances, well-known structures, materials, or operations have not been shown or described in detail to avoid obscuring aspects of the embodiments.

It will be understood that each block of the schematic flowcharts and / or schematic block diagrams, and combinations of blocks in the schematic flowcharts and / or schematic block diagrams, can be implemented by code. The code can be provided to a processor of a general-purpose computer, special-purpose computer, or other programmable data processing apparatus to generate machinery, such that instructions executable via the processor of the computer or other programmable data processing apparatus, create means for implementing the functions / operations specified in the blocks or blocks of the schematic flowcharts and / or schematic block diagrams.

[0039] The code can also be stored in a storage device that can instruct a computer, other programmable data processing device or other device to operate in a particular manner, such that the instructions stored in the storage device produce an article of art that implements the function / action specified in blocks or blocks of a schematic flowchart and / or schematic block diagram.

[0040] The code may also be loaded onto a computer, other programmable data processing apparatus or other device to cause a series of operational steps to be performed on the computer, other programmable apparatus or other device to produce a computer-implemented process, such that the code executing on the computer or other programmable apparatus provides a process for implementing the functions / actions specified in blocks or blocks of flowcharts and / or block diagrams.

[0041] The schematic flowcharts and / or schematic block diagrams in the accompanying drawings illustrate the architecture, functionality, and operation of possible implementations of apparatus, systems, methods, and program products according to various embodiments. In this regard, each block in the schematic flowcharts and / or schematic block diagrams may represent a module, segment, or portion of code, which includes one or more executable instructions for implementing a specified logical function.

[0042] It should also be noted that in some alternative implementations, the functions annotated in the blocks may occur in a different order than those annotated in the figures. For example, depending on the functions involved, two blocks shown consecutively may actually be executed substantially simultaneously, or these blocks may sometimes be executed in reverse order. Other steps and methods are conceivable that are functionally, logically, or effectively equivalent to one or more blocks or portions thereof in the illustrated figures.

[0043] While various arrow and line types may be used in flowcharts and / or block diagrams, it should be understood that they do not limit the scope of the respective embodiments. In fact, some arrows or other connectors may be used solely to indicate the logical flow of the depicted embodiment. For example, an arrow may indicate a wait or monitoring period of unspecified duration between enumeration steps in a depicted embodiment. It will also be noted that each block of the block diagram and / or flowchart, and combinations of blocks in the block diagram and / or flowchart, can be implemented by a system based on dedicated hardware, or a combination of dedicated hardware and code, performing a specific function or operation.

[0044] The description of the elements in each figure can be referenced to the elements in the preceding figures. Throughout all figures, the same numbers refer to the same elements, including alternative embodiments of the same elements.

The transmitters 210 and receivers 212 can be of any suitable type. In one embodiment, the transmitters 210 and receivers 212 can be part of a transceiver.

[0063] Figure 3 An embodiment of a device 300 that can be used for transmission power control is depicted. Device 300 includes one embodiment of a network unit 104. Furthermore, network unit 104 may include a processor 302, a memory 304, an input device 306, a display 308, a transmitter 310, and a receiver 312. It will be understood that the processor 302, memory 304, input device 306, display 308, transmitter 310, and receiver 312 may be substantially similar to the processor 202, memory 204, input device 206, display 208, transmitter 210, and receiver 212 of remote unit 102, respectively.

[0064] In some embodiments, transmitter 310: transmits first scheduling information for a first uplink transmission on a first serving cell at a first time, wherein the first scheduling information includes a first transmission period and a first parameter set; and transmits second scheduling information for a second uplink transmission on a second serving cell at a second time.

[0066] Although only one transmitter 310 and one receiver 312 are illustrated, network unit 104 can have any suitable number of transmitters 310 and receivers 312. Transmitters 310 and receivers 312 can be of any suitable type. In one embodiment, transmitters 310 and receivers 312 can be part of a transceiver.

[0067] As used herein, in some embodiments, the TX and RX beam correspondence configured at the TRP and UE can be maintained as follows: the TX and RX beam correspondence at the TRP can be maintained if at least one of the following is satisfied: 1) the TRP is able to determine the TRP RX beam for uplink reception based on downlink measurements of the UE on one or more TX beams of the TRP; and 2) the TRP is able to determine the TRP TX beam for downlink transmission based on uplink measurements of the TRP on one or more RX beams of the TRP; and the TX and RX beam correspondence at the UE can be maintained if at least one of the following is satisfied: 1) the UE is able to determine the UE TX beam for uplink transmission based on downlink measurements of the UE on one or more RX beams of the UE; and the UE is able to determine the UE RX beam for downlink reception based on an indication from the TRP based on uplink measurements of one or more TX beams of the UE.

[0068] Furthermore, as used herein, an antenna port can be defined such that the channel through which a symbol on the same antenna port is transmitted can be inferred from the channel through which another symbol on the same antenna port is transmitted.

[0069] Furthermore, as used herein, two antenna ports can be considered as QCLs if the large-scale properties of the channel through which symbols on one antenna port are transmitted can be inferred from the channel through which symbols on the other antenna port are transmitted. Large-scale properties may include one or more of delay spread, Doppler spread, Doppler shift, average gain, average delay, and spatial RX parameters. Additionally, two antenna ports may be QCLs relative to a subset of large-scale properties. Furthermore, spatial RX parameters may include one or more of the following: AoA, dominant AoA, average AoA, angular spread, PAS of AoA, average AoD, PAS of AoD, transmit and / or receive channel correlation, transmit and / or receive beamforming, spatial channel correlation, etc.

[0070] As used herein, an antenna port can be a logical port that corresponds to a beam (e.g., generated by beamforming) or a physical antenna on the device. In some embodiments, a physical antenna can be directly mapped to a single antenna port. In such embodiments, the antenna port corresponds to an actual physical antenna. In some embodiments, a set of physical antennas, a subset of physical antennas, an antenna set, an antenna array, and / or an antenna subarray can be mapped to one or more antenna ports after applying complex weights, cyclic delays, or both to the signal on each physical antenna. In some embodiments, a physical antenna set can have antennas from a single module, a single panel, multiple modules, or multiple panels. Weights can be fixed, as in antenna virtualization schemes such as CDD. The process for determining the antenna port corresponding to a physical antenna may be device-specific and may be transparent to other devices.

[0071] In some examples, the DL TX antenna port may correspond to the antenna port of a single CSI-RS resource, or to the antenna ports of different CSI-RS resources (e.g., including a first subset of at least one DL TX antenna port corresponding to a first CSI-RS resource, and a second subset of at least one DL TX antenna port corresponding to a second CSI-RS resource).

[0072] In some embodiments, a DL TX antenna port may be associated with one or more SS blocks. In such embodiments, each SS block may have a corresponding SS block index (e.g., a number or value indicating the SS block). In various embodiments, an antenna port associated with a first SS block (e.g., having a first SS block index) may correspond to a first DL TX beam (e.g., a beamforming pattern), and an antenna port associated with a second SS block (e.g., having a second SS block index) may correspond to a second DL TX beam. In such embodiments, depending on the SS block, the antenna port may correspond to different DL TX beams (e.g., a first DL TX beam or a second DL TX beam). It is understood that the first DL TX beam may be different from the second DL TX beam. Furthermore, the first SS block may be different from the second SS block, resulting in the first SS block index being different from the second SS block index. In some embodiments, the first SS block and the second SS block transmission instances may completely or at least partially overlap. In one embodiment, the UE may assume that any transmission instance of an SS block with the same SS block index is transmitted on the same antenna port. In some embodiments, the UE may not assume that a channel through which a first SS block with the first SS block index is transmitted can be inferred from a channel through which a second SS block with a second SS block index (e.g., the second SS block index is different from the first SS block index) is transmitted, even if the first SS block and the second SS block are transmitted on the same antenna port.

[0073] In various embodiments, a DL TX antenna port may be associated with one or more CSI-RS resources. In some embodiments, an antenna port associated with a first CSI-RS resource (e.g., having a first CSI-RS resource index) may correspond to a first DL TX beam (e.g., a beamforming pattern), and an antenna port associated with a second CSI-RS resource (e.g., having a second CSI-RS resource index) may correspond to a second DL TX beam. In such embodiments, depending on the CSI-RS resource, the antenna port may correspond to different DL TX beams (e.g., a first DL TX beam or a second DL TX beam). It is understood that the first DL TX beam may be different from the second DL TX beam. TX beam. Furthermore, the first CSI-RS resource may differ from the second CSI-RS resource, resulting in a different first CSI-RS resource index from the second CSI-RS resource index. In some embodiments, the first CSI-RS resource may be transmitted at a first time instance and the second CSI-RS resource may be transmitted at a second time instance. In other embodiments, the transmission instances of the first and second CSI-RS resources may completely or at least partially overlap. In one embodiment, the UE may assume that any transmission instance of a CSI-RS resource with the same CSI-RS resource index is transmitted on the same antenna port. In some embodiments, the UE may not assume that a channel transmitting a first CSI-RS resource with a first CSI-RS resource index can be inferred from a channel transmitting a second CSI-RS resource with a second CSI-RS resource index (e.g., the second CSI-RS resource index is different from the first CSI-RS resource index), even if the first and second CSI-RS resources are transmitted on the same antenna port.

[0074] In various configurations, such as 5G NR RAT supporting both single-carrier and multi-carrier operation, the UE can communicate with one or more serving cells to enhance coverage, facilitate efficient spectrum use, support various network deployments, access different services, and / or access different service types. In such configurations, the CA can provide a framework for the UE to operate coherently with multiple CCs. In some configurations, the CA may have three different operating modes: in-band continuous CA, in-band discontinuous CA, and inter-band CA. In some embodiments, such as for in-band continuous CA and / or in-band discontinuous CA, the UE may have a single PA for operating on one or more CCs. In various embodiments, such as for inter-band CA and / or in-band discontinuous CA, the UE may have different PAs for operating on one or more CCs.

[0075] In some configurations, such as within the LTE-CA framework, there may be one or more fixed time slots, subframe sizes, fixed parameter sets, SCS, and / or fixed license-to-transmission timing offsets for different serving cells. In various configurations, such as for in-band continuous CA, the UE can handle delay spreads up to 0.26 µs across different component carriers (e.g., monitored at the receiver), and for in-band discontinuous CA and inter-band CA, the UE can handle delay spreads up to 30.26 µs across different component carriers (e.g., monitored at the receiver). Such delay spreads up to 30.26 µs can be at most half the length of an LTE symbol.

[0076] In various configurations, such as in the 5G-NR CA framework, the slot size may vary (e.g., the slot size may have 2 to 14 symbols), the parameter set and / or SCS may differ, and / or the permitted transmission timing offset may differ for different serving cells. In some configurations, multiple services with different performance requirements and / or priorities can be provided. Therefore, in some embodiments, a UE operating via NR-CA can use multiple heterogeneous UL transmissions for different serving cells. These heterogeneous UL transmissions can be categorized as (i) slot-level synchronization and / or symbol-level synchronization, and / or (ii) slot-level asynchrony and / or symbol-level asynchrony. It is understood that the start time of different UL transmissions for different serving cells can differ. Therefore, various heterogeneous overlapping UL transmissions can be classified as slot-level asynchrony and / or symbol-level asynchrony. Therefore, a UE (e.g., in the 5G-NR CA framework) can be designed to handle transmission timing offsets up to 500µs between two CGs.

[0077] In various embodiments, a missing element in various solutions for heterogeneous UL transmissions (e.g., in the 5G-NR CA framework) may be a sudden phase change in the PA, which could be caused by a sudden change from a certain total power level in one transmission set to a different total power level in another transmission set, and may not be addressed. This sudden phase change invalidates previous channel estimations and prevents coherent demodulation facilitated by previous DMRS from being applied to the second transmission set. Note that unperforated DMRS or maintaining a constant power for the DMRS does not solve this problem. As described herein, a fixed total power can be maintained for the power amplifier to avoid phase discontinuities, or, if a sudden power change and / or phase change / discontinuity exists, an “additional” DMRS can be inserted into the transmission, for example, at the beginning of the second transmission set (and typically immediately after any sudden power change to the PA).

[0078] In some embodiments, appropriate power allocation for UE transmissions may be important to facilitate various heterogeneous UL transmissions that overlap in time and each have certain SINR requirements. In some embodiments, the UE can ensure that it adheres to the maximum transmission power level of each serving cell and the total power level of all serving cells set by the network, regardless of the operating mode and the various heterogeneous UL transmissions.

[0079] For UEs operating in a CA-based wireless network with multiple CCs (e.g., 5G NR), the various methods described in this paper propose power allocation methods for overlapping UL transmissions with different durations, required power levels, and / or priorities for UEs with single or multiple PAs, as well as qualitative criteria for the network / UE to select an appropriate method based on the properties of different transmissions. Among these methods, a key focus is likely on ensuring proper channel estimation and that coherent decoding is always guaranteed, regardless of varying transmission power and the resulting phase discontinuities.

[0080] The various methods described herein relate to configurations in which the UE simultaneously performs one or more heterogeneous UL transmissions (e.g., slot-based PUSCH, non-slot-based PUSCH, long PUCCH, short PUCCH, multiplexing of the same SCS in UL transmissions and / or different SCS in UL transmissions). The one or more heterogeneous UL transmissions overlap at least partially or completely in time, and each UL transmission of the one or more heterogeneous UL transmissions may have different durations, different required transmit powers, and / or different priorities. The one or more heterogeneous UL transmissions may occur within a serving cell and / or across different serving cells with different carrier frequencies. The different carrier frequencies may be in the same frequency band or different frequency bands. In one embodiment, if the one or more heterogeneous transmissions occur within a cell or across different cells with consecutive CAs and / or co-located cells within a band, the symbol timing of a UL transmission with a longer symbol duration may be aligned with the symbol timing of another UL transmission with a shorter symbol duration (e.g., if the serving cells are in the same TAG). In another embodiment, if one or more heterogeneous transmissions occur across different cells that span in-band non-contiguous CA and / or non-co-located cells, the symbol timing of a UL transmission with a longer symbol duration may not be aligned with the symbol timing of another UL transmission with a shorter symbol duration (e.g., if the serving cells are in different TAGs). In some embodiments, the UE may use one PA for multiple transmissions within a cell or across aggregated carriers for in-band contiguous CA and / or in-band non-contiguous CA, while the UE may use separate PAs for inter-band CA and in-band non-contiguous CA.

[0081] Figure 4This is a schematic block diagram illustrating one embodiment of a system 400 including overlapping transmissions. System 400 includes a first UL transmission 402 (“UL1”) occurring during a first transmission period 404 (“T1”) and a second UL transmission 406 (“UL2”) occurring during a second transmission period 408 (“T2”). The first transmission period 404 may have a longer duration than the second transmission period 408. Furthermore, the first transmission period 404 at least partially overlaps or completely overlaps with the second transmission period 408 in time.

[0082] In some embodiments, a UE with CA capability may be scheduled for the first UL transmission 402 and the second UL transmission 406 (e.g., via licensed scheduling or unlicensed scheduling). The first UL transmission 402 may have a first parameter set and / or SCS ("μ1") and a first transmit power ("P1") on a first serving cell ("c1") on a first component carrier ("CC1"). In various embodiments, the first UL transmission 402 may be used for eMBB and / or slot-based PUSCH. The second UL transmission 406 may have a second parameter set and / or SCS ("μ2") and a second transmit power ("P2") on a second serving cell ("c2") on a second component carrier ("CC2"). In some embodiments, the second UL transmission 406 may be used for URLLC and / or PUCCH. In some embodiments, the second UL transmission 406 may have a higher priority than the first UL transmission 402. In various embodiments, the slot timing and / or symbol timing of c1 and c2 are asynchronous for the UE. Therefore, even if the serving cells have a common parameter set and / or SCS, the UE receiver detects different DL slot boundaries and / or symbol boundaries for c1 and c2. Regarding Figures 5 to 9 Various methods for a UE to perform two heterogeneous UL transmissions using a single PA are described.

[0083] Figure 5 This is a schematic block diagram of one embodiment of the timing diagram 500 illustrating power settings. Timing diagram 500 illustrates [something related to power settings]. Figure 4 The first transmission power 502 of the first UL transmission 402 described herein is used for Figure 4 The second transmission power 504 of the second UL transmission 406 described herein, and the total transmission power 506 which is the sum of the first transmission power 502 and the second transmission power 504, are also described. Furthermore, timing diagram 500 illustrates a first time 508, a second time 510, a third time 512, and a fourth time 514. The first time 508 corresponds to the start time of the first UL transmission 402, and the fourth time 514 corresponds to the end time of the first UL transmission 402. Therefore, Figure 4The first transmission period 404 is equal to the time between the first time 508 and the fourth time 514. Furthermore, the second time 510 corresponds to the start time of the second UL transmission 406, and the third time 512 corresponds to the end time of the second UL transmission 406. Therefore, Figure 4 The second transmission period 408 is equal to the time between the second time 510 and the third time 512.

[0084] exist Figure 5 In the illustrated embodiment, the UE attempts to keep the total transmission power 506 constant during a first transmission period 404 that includes a second transmission period 408. In one embodiment, a first UL transmission 402 is scheduled before the second UL transmission 406, and the UE determines the power setting based on a first power requirement P1 of the first UL transmission 402, without considering the power requirement P2 of the second UL transmission 406.

[0085] As illustrated, the UE may transmit the first N1 symbols of the first UL transmission 402 at power P1 (e.g., a duration less than the first transmission period 404) before and until the start of the second UL transmission 406. Therefore, between the first time 508 and the second time 510, the first transmission power 502 is equal to P1. In some embodiments, the duration between the first time 508 and the second time 510 may be in units corresponding to the symbol duration of the first UL transmission 402. The symbol duration may be based on a first parameter set and / or subcarrier spacing μ1. In some embodiments, the UE implementation may determine whether and what waveform to transmit between the end of the last symbol (e.g., a symbol boundary) of the N1 symbols of the first UL transmission 402 just before the start of the second UL transmission 406 and the start of the first symbol of the second UL transmission 406, to facilitate appropriate decoding using the first DMRS (“DMRS1”) within the first N1 symbols. In one embodiment, the first DMRS is transmitted at or near the beginning of the first UL transmission 402 (e.g., preloaded near the beginning of the first N1 symbols).

[0086] During the second transmission period 408, the UE can use power The second UL transmission 406 is then sent. Therefore, between the second time 510 and the third time 512, the second transmission power 504 is equal to the minimum of P1 and P2. Because the second transmission period 408 begins at the second time 510 and ends at the third time 512, the second transmission power 504 is equal to zero between the first time 508 and the second time 510, and between the third time 512 and the fourth time 514.

[0087] During the first transmission period 404 between the second time 510 and the third time 512, the first transmission power 502 is equal to the maximum value of 0 and P1 minus P2 (e.g., Max{0, P1-P2}) or equivalent to 0 and P1 minus P2. (For example, The maximum value. Therefore, if P1≤P2 (or If the UE can stop the transmission of the first UL transmission 402 during the duration of T2 (e.g., the portion and / or duration of the overlapping transmission between UL1 and UL2, which may also include a portion of the duration of the UL1 symbol as overlapping transmission time immediately before and / or after the UL2 transmission to account for any misalignment of symbol boundaries between UL1 and UL2), and resume the first UL transmission 402 with a power of P1 for the second N2 symbols after the completion of the second UL transmission 406 (with the same symbol timing as the first N1 symbols of the transmitted UL1). In other words, during the first transmission period 404 between the third time 512 and the fourth time 514, the first transmission power 502 is equal to P1. Therefore, for the duration of the first transmission period 404, the total transmission power 506 of PA is fixed at P1 (e.g., constantly maintained at P1). Therefore, for the duration of the first transmission period 404, there may be no phase discontinuity between the transmission of the first N1 symbols of the first UL transmission 402 and the transmission of the second N2 symbols of the first UL transmission 402 (e.g., symbols following the duration T2). In one embodiment, some subcarriers (e.g., REs) of the OFDM and / or DFTS-OFDM symbols of the first UL transmission 402 may be reserved in advance (e.g., the UE performs rate matching around those reserved subcarriers), and the UE may use those reserved subcarriers to send an indication to a network entity (e.g., gNB) to indicate whether puncturing of the first UL transmission 402 is performed due to power limitations (e.g., by sending an indication to cell c1 with a flag “F1” set to zero to indicate puncturing; in one example, F1 (e.g., having one or more bits) may represent a power offset corresponding to any change in the UL1 transmission power during the overlap duration T2, in the case where one of the states of F1 indicates puncturing).

[0088] Furthermore, if P1 > P2 (or Then the UE can adjust and / or scale the first UL transmission 402 so that the first transmission power 502 is equal to the first UL transmission power 402 during T2. After completing the second UL transmission 406, for the second N2 symbols of the first UL transmission 402, the UE can readjust and / or rescale the first UL transmission 402 back to a first transmission power 502 equal to P1. In one embodiment, the UE can send an indication to cell c1 with a flag F1=1 indicating no perforation. It is understood that because the PA power setting remains constant for duration T1, the preceding demodulation reference signal DMRS1 can facilitate coherent decoding of UL1.

[0089] Figure 6 This is a schematic block diagram of another embodiment of the timing diagram 600 illustrating power settings. Timing diagram 600 illustrates a method for... Figure 4 The first transmission power 602 of the first UL transmission 402 described herein is used for Figure 4 The second transmission power 604 of the second UL transmission 406 described herein, and the total transmission power 606 which is the sum of the first transmission power 602 and the second transmission power 604, are also described. Furthermore, timing diagram 600 illustrates a first time 608, a second time 610, a third time 612, and a fourth time 614. The first time 608 corresponds to the start time of the first UL transmission 402, and the fourth time 614 corresponds to the end time of the first UL transmission 402. Therefore, Figure 4 The first transmission period 404 is equal to the time between the first time 608 and the fourth time 614. Furthermore, the second time 610 corresponds to the start time of the second UL transmission 406, and the third time 612 corresponds to the end time of the second UL transmission 406. Therefore, Figure 4 The second transmission period 408 is equal to the time between the second time 610 and the third time 612.

[0090] exist Figure 6 In the embodiment illustrated in the figure, the UE's goal is not a constant total transmission power 606 during the first transmission period 404, which includes the second transmission period 408, but rather... Figure 5 The illustrated embodiment can transmit a higher power level to the second UL 406 assignment compared to the previous embodiment. Furthermore, Figure 6 The illustrated embodiment attempts to avoid piercing the first UL transmission 402, thus requiring the insertion of an additional DMRS when the total transmission power 606 changes.

[0091] As illustrated, the UE may transmit the first N1 symbols of the first UL transmission 402 at power P1 before and until the start of the second UL transmission 406 (e.g., its duration is less than the first transmission period 404). Therefore, between the first time 608 and the second time 610, the first transmission power 602 is equal to P1. In one embodiment, the first DMRS is transmitted at or near the start of the first UL transmission 402 (e.g., preloaded near the start of the first N1 symbols).

[0092] During the second transmission period 408, the UE can transmit the second UL transmission 406 with power P2. Therefore, between the second time 610 and the third time 612, the second transmission power 604 is equal to P2. Because the second transmission period 408 begins at the second time 610 and ends at the third time 612, the second transmission power 604 is equal to zero between the first time 608 and the second time 610, and between the third time 612 and the fourth time 614.

[0093] During the first transmission period 404 between the second time 610 and the third time 612, the first transmission power 602 is equal to Min{Max{0,P} CMAX,c1 -P2},P1}. Furthermore, during the first transmission period 404 between the third time 612 and the fourth time 614, the first transmission power 602 is equal to Min{Max{P2,P...}. CMAX,c1}, P1+P2}. Therefore, if P2≥P CMAX,c1 , where P CMAX,c1 If the maximum configured output power of serving cell c1 is true, then the UE can stop the first UL transmission 402 during the duration of T2, and after the completion of the second UL transmission 406, it can resume transmission at a power equal to... The first transmission power 602 resumes the first UL transmission 402. In one embodiment, the UE may send an indication (e.g., flag F2 = 0) to cell c1 to indicate puncture. This is because the UE output power setting changes from P1 to P2 during the first UL transmission 402. Therefore, the UE can multiplex the additional demodulation reference signal (“DMRS2”) into the first UL transmission 402 to facilitate coherent decoding after the total power transmission 606 is changed at the third time 612. It is understood that with the change in PA power setting, the phase of the output signal may change abruptly, resulting in phase discontinuities, and therefore, the new DMRS can be used to enable the gNB receiver to update its phase estimate. For example, the UE may not transmit (e.g., punctured) scheduled data on some or all of the OFDM and / or DFTS-OFDM symbols of the first UL transmission 402 immediately following the second UL transmission 406, and may transmit DMRS2 on those subcarriers. It is understood that if The power boost for the remaining transmission time of the first UL transmission 402 after the third time 612 can compensate for the potential performance loss due to the power reduction (e.g., puncture) that occurs during the overlap duration T2.

[0094] Furthermore, if P2 < P CMAX，c1 And P CMAX，c1 If -P2 < P1, then the UE can adjust the first UL transmission 402 so that the first transmission power 602 is equal to the first UL transmission power during T2. After completing the second UL transmission 406, the UE can readjust the first UL transmission 402 so that the first transmission power 602 equals P. CMAX，c1 The first UL transmission 402 is then completed. In some embodiments, the UE may send an indication to cell c1 to indicate potential puncturing if additional signals, such as additional DMRS, are transmitted (e.g., flag F2 = 1). This is because the UE output power setting changes from P1 to P during the first UL transmission 402. CMAX，c1 Therefore, the UE can multiplex the additional demodulation reference signal DMRS2 into the first UL transmission 402 to facilitate coherent decoding after the total power transmission 606 is changed at the second time 610.

[0095] Furthermore, if P2 < P CMAX，c1 And P CMAX，c1If -P2≥P1, then the UE can continue transmitting the first UL transmission 602 at a first transmission power 602 equal to P1 during T2. After completing the second UL transmission 406, the UE can readjust the first UL transmission 402 so that the first transmission power 602 equals P1+P2 and complete the first UL transmission 402. (The UE can send an indication to cell c1, e.g., flag F2=1). In some embodiments, the UE can send an indication to cell c1 to indicate puncturing (e.g., flag F2=1). Because the UE output power setting changes from P1 to P1+P2 during the first UL transmission 402, the UE can multiplex the additional demodulation reference signal DMRS2 into the first UL transmission 402 to facilitate coherent decoding after changing the total power transmission 606 at the second time 610. Between the first time 608 and the second time 610, the total power transmission 606 is equal to P1, and between the second time 610 and the fourth time 614, the total power transmission 606 is equal to Min{P1+P2}. CMAX，c1 ,P1+P2}.

[0096] Figure 7 This is a schematic block diagram of yet another embodiment of the timing diagram 700 illustrating power settings. Timing diagram 700 illustrates a method for... Figure 4 The first transmission power 702 of the first UL transmission 402 described herein is used for Figure 4 The second transmission power 704 of the second UL transmission 406 described herein, and the total transmission power 706 which is the sum of the first transmission power 702 and the second transmission power 704, are also described. Furthermore, timing diagram 700 illustrates a first time 708, a second time 710, a third time 712, and a fourth time 714. The first time 708 corresponds to the start time of the first UL transmission 402, and the fourth time 714 corresponds to the end time of the first UL transmission 402. Therefore, Figure 4 The first transmission period 404 is equal to the time between the first time 708 and the fourth time 714. Furthermore, the second time 710 corresponds to the start time of the second UL transmission 406, and the third time 712 corresponds to the end time of the second UL transmission 406. Therefore, Figure 4 The second transmission period 408 is equal to the time between the second time 710 and the third time 712.

[0097] exist Figure 7 In the illustrated embodiment, the UE's goal is not a constant total transmission power 706 during the first transmission period 404, which includes the second transmission period 408, but rather... Figure 6 Unlike the illustrated embodiment, the UE attempts to assign the maximum available power level to each UL transmission, thereby reducing the chance of repeatedly puncturing one or more symbols of the first UL transmission 402, but additional DMRS is required each time the total transmission power 706 changes.

[0098] As illustrated, the UE may transmit the first N1 symbols of the first UL transmission 402 at power P1 before and until the start of the second UL transmission 406 (e.g., its duration is less than the first transmission period 404). Therefore, between the first time 708 and the second time 710, the first transmission power 702 is equal to P1. In one embodiment, the first DMRS is transmitted at or near the start of the first UL transmission 402 (e.g., preloaded near the start of the first N1 symbols).

[0099] During the second transmission period 408, the UE can transmit the second UL transmission 406 with power P2. Therefore, between the second time 710 and the third time 712, the second transmission power 704 is equal to P2. Because the second transmission period 408 begins at the second time 710 and ends at the third time 712, the second transmission power 704 is equal to zero between the first time 708 and the second time 710, and between the third time 712 and the fourth time 714.

[0100] During the first transmission period 404 between the second time 710 and the third time 712, the first transmission power 702 is equal to Min{P} CMAX，c1 P CMAX，total -P2, (1+γ)P1}. Furthermore, during the first transmission period 404 between the third time 712 and the fourth time 714, the first transmission power 702 is equal to Min{P CMAX，c1 ,(1+γ)P1}。 Therefore, if P2=P CMAX，total , where P CMAX。total This is the total and / or aggregated output power for the maximum configuration across all cells (e.g., CC1 and CC2 in this example) for carrier aggregation or dual connectivity (e.g., the P value used for CA in subframe and / or slot index i, as noted in the 3GPP LTE and / or NR specifications). CMAX (i1), or P for DC in subframe and / or time slot pair indices i1 and i2. CMAX (i1, i2)), then the UE can stop transmitting the first UL transmission 402 during the duration T2, and after completing the second UL transmission 406, it can stop transmitting at a time equal to (i1, i2)). The first transmission power 702 resumes the first UL transmission 402. In one embodiment, the UE may send an indication (e.g., flag F3 = 0) to cell c1 to indicate puncture. Because during the first UL transmission 402, the UE's total output power setting changes from P1 to P2 (= P... CMAX,total And then it becomes Furthermore, the UE stops the first UL transmission 402 during T2, so the UE can multiplex the additional demodulation reference signal DMRS2 into the first UL transmission 402 (e.g., when the first transmission power 702 equals...). (during the duration of the duration) to facilitate coherence following the change in total power transmission 706 at the third time 712. The UE may not transmit (e.g., punctured) scheduled data on some or all of the OFDM and / or DFTS-OFDM symbols of the first UL transmission 402 immediately following the completion of the second UL transmission 406, and may transmit DMRS2 on these subcarriers.

[0101] Furthermore, if P2 < P CMAX,total Then the UE can adjust the first UL transmission power 402 so that during T2 the first transmission power 702 equals Where γ≥ is the maximum power enhancement factor of the first UL transmission 402. After completing the second UL transmission 406, the UE can readjust the first UL transmission 402 so that the first transmission power 702 equals The first UL transmission 402 is then completed. In some embodiments, the UE may send an indication to cell c1 to indicate potential punching if additional signals, such as additional DMRS, are transmitted (e.g., flag F3 = 1). This is because the UE output power setting changes from P1 to P2 during the first UL transmission 402. And then changed again to Therefore, the UE can multiplex two additional demodulation reference signal sets, DMRS2 and DMRS3, into the first UL transmission 402 to facilitate coherent decoding after each instance of changing the total output power setting (e.g., immediately after the start time of the second UL transmission 406—second time 712, and immediately after the completion time of the second UL transmission 406—third time 714). In some embodiments, one motivation for increasing the power level of the first UL transmission 402 and assigning a power level larger than the original configuration power P1 is to increase the reliability of the first UL transmission 402 as much as possible by increasing the transmission power and to minimize and / or compensate for any adverse effects on the performance of the first UL transmission 402 caused by puncturing the data of the first UL transmission 402 to insert additional DMRSs. Between the first time 708 and the second time 710, the total power transmission 706 is equal to P1, and between the second time 710 and the third time 712, the total power transmission 706 is equal to Min{P}. CMAX,c1 +P2,P CMAX,total ,(1+γ)P1+P2}, and the total power transfer 706 between the third time 712 and the fourth time 714 is equal to Min{P CMAX,c1 ,(1+γ)P1}.

[0102] In the various embodiments described herein, flags F1, F2, and / or F3 may include one or more bits and may represent a power offset term corresponding to any change in the transmit power of the first UL transmission 402 during the overlap between the first transmission period 404 and the second transmission period 408. In such embodiments, one of the states of flags F1, F2, and / or F3 may indicate punching or no transmission.

[0103] exist Figures 5 to 7 The various embodiments described herein can be applied to configurations where the slot timing and / or symbol timing of the first and second serving cells are synchronized. In such a configuration, for a given set of parameters and / or SCS, the UE receiver can detect the same DL slot boundaries and / or symbol boundaries for both the first and second serving cells. In some embodiments, if a symbol of a UL transmission having a first symbol duration partially or completely overlaps with one or more symbols of another UL transmission having a second symbol duration, and if it is necessary to adjust the transmission power of the symbol with the first symbol duration (e.g., to reduce power or not transmit) to accommodate the other UL transmission with the second symbol duration, the adjusted power can be applied to the entire symbol with the first symbol duration.

[0104] also, Figures 5 to 7 The various embodiments described herein can be applied to configurations where there is partial overlap between the first UL transmission and the second UL transmission (e.g., if only a portion of the duration T2 of the second UL transmission 406 overlaps with the first UL transmission 402). In some embodiments, the UE can apply Figures 5 to 7 The various embodiments described herein, except that the operations and / or procedures described for the overlap time may only apply to a partial overlap duration, and the operations and / or procedures described for the remaining symbols of the first UL transmission 402 after the completion of the second UL transmission 406 may not be necessary if there is no remaining first UL transmission 402 after the partial overlap duration.

[0105] In addition, Figures 5 to 7 In the various embodiments described herein, in order for the gNB to decode heterogeneous transmissions in light of sudden power changes, the gNB may estimate the RX power change (or an estimate of the TX power difference between the estimated UL1 and UL2 transmissions based on the PHR), and then scale the LLR to account for the power change used for the first UL transmission 402.

[0106] Figures 5 to 7 The various embodiments described herein can differently affect the performance corresponding to the first UL transmission 402 and the second UL transmission 406. Therefore, the gNB can determine which to use Figures 5 to 7 One of the embodiments described herein, and the determined embodiment can be indicated to the UE based on the configuration of two concurrent UL transmissions. The gNB can determine the embodiment to be used based on the following: the gNB's estimate of the power P1 of the first UL transmission 402 and the maximum configured power P for the serving cell c1. CMAX，c1 The difference between them; the maximum total power and / or aggregated power P of the configuration across two serving cells. CMAX，total The maximum configured power P of the service cell c1 CMAX，c1 The difference between; the power P2 used for the second UL transmission 406; the duration T2 of the second UL transmission 406; the number of symbols left for the first UL transmission 402 after the completion of the second UL transmission 406; and / or the content of the symbols at the start and / or end times of the second UL transmission 406 (e.g., whether the symbols include UCI).

[0107] In one embodiment, the gNB can configure the UE to use based on higher-layer signaling (e.g., using MAC control elements, using RRC signaling, etc.). Figures 5 to 7 One of the embodiments described herein. In another example, the UE may determine and indicate to the gNB (e.g., dynamically, semi-dynamically, and / or semi-statically) which method it will select based on the configuration of two UL transmissions including the above aspects.

[0108] In some embodiments, if P1 has a value close to P CMAX，c1 The values ​​(e.g., P1 and P) CMAX，c1 If the difference between them is less than a predetermined threshold, then the UE can use about Figure 5 The described embodiments. In some embodiments, if the symbol of the first UL transmission 402 near the start and / or end time of the second UL transmission 406 includes a UCI, the UE can adopt regarding Figure 5 The described embodiments are designed to reduce abrupt power and / or phase changes, which may require perforated UCI symbols to insert additional DMRS. In various embodiments, if P CMAX，c1 and P CMAX，total If the difference between the two is small (e.g., less than the first threshold), the duration T2 of the second UL transmission 406 is small (e.g., less than the second threshold), and / or a small number of symbols are left for the first UL transmission 402 after the completion of the second UL transmission 406 (e.g., less than the third threshold), then the UE can use the following... Figure 6 The described embodiments aim to reduce repeated perforations in the first UL transmission 402. In some embodiments, if P CMAX，c1 and P CMAX，totalIf the difference between the two is large (e.g., greater than the first threshold), P2 is large (e.g., greater than the second threshold), the duration T2 for the second UL transmission 406 is large (e.g., greater than the third threshold), and / or many symbols are left for the first UL transmission 402 after the second UL transmission 406 is completed (e.g., greater than the fourth threshold), then the UE can use the following... Figure 7 The described embodiments are intended to provide a power boost for the first UL transmission 402 and / or reduce performance loss due to high power and prolonged overlap with the second UL transmission. In yet another example, if almost no symbols are left (e.g., less than a certain threshold), or if the corresponding power allocation in the second or third method or its variants is small (e.g., less than another specific threshold), the UE may stop / discard the first UL transmission after the second transmission is completed.

[0109] In some embodiments, a second UL transmission 406 having a transmission power P2 (e.g., also having a shorter transmission duration and / or higher priority than the first UL transmission 402) can occur semi-persistently within the first UL transmission 402. For example, the second UL transmission 406 may include a short PUCCH carrying HARQ-ACK feedback for a slotless PDSCH based on semi-persistent scheduling; therefore, the UE can determine whether the first UL transmission 402 overlaps with the second UL transmission 406 in the Min{Max{0,P} event. CMAX,c1 -P2},P1} and Min{P CMAX,c1 The first UL transmission 402 power is changed between P1 and P2 (e.g., during the overlap period, the Min{Max{0,P} power is changed).

[0110] In various embodiments, if the UE uses multiple power amplifiers to perform one or more heterogeneous uplink transmissions (e.g., for inter-band CA or possibly intra-band discontinuous CA), a constant PA power setting can be determined for each PA throughout the transmission duration, or the power setting can be changed by inserting additional DMRS. Figure 8 In the illustrated embodiment, the UE can fully puncture the first UL transmission 402 during T2, and can boost the transmission power to P1' (≤P) when the second UL transmission 406 is completed. cmax，c1 (And additional DMRS can be multiplexed for new phase and / or channel estimation). In such an embodiment, the power boost for the remaining transmission time of the first UL transmission 402 can compensate for potential performance loss due to puncturing during T2. Figure 9In the embodiment illustrated, the UE can adjust the transmit power of the first UL transmission 402 from P1 to Min{Max{0,P CMAX,c1 -P2},P1}, where P1 and the new power level Min{Max{0,P CMAX,c1 The difference between P2 and P1 may be insignificant (e.g., less than a configured, predefined, and / or dynamically signaled threshold), and the adjusted transmit power is maintained until the first UL transmission 402 ends. It is understood that by maintaining the same adjusted transmit power for the remaining transmissions, the UE can rely on a single additional DMRS2 for coherent demodulation during and after the overlap with the second UL transmission 406, and can avoid the insertion of further additional DMRSs (i.e., a set of at least two additional DMRSs in total).

[0111] Figure 8 This is a schematic block diagram of yet another embodiment of the timing diagram 800 illustrating power settings. Timing diagram 800 illustrates... Figure 4 The first transmission power 802 of the first UL transmission 402 described herein is used for Figure 4 The second transmission power 804 of the second UL transmission 406 described herein, and the total transmission power 806 which is the sum of the first transmission power 802 and the second transmission power 804, are also described. Furthermore, timing diagram 800 illustrates a first time 808, a second time 810, a third time 812, and a fourth time 814. The first time 808 corresponds to the start time of the first UL transmission 402, and the fourth time 814 corresponds to the end time of the first UL transmission 402. Therefore, Figure 4 The first transmission period 404 is equal to the time between the first time 808 and the fourth time 814. Furthermore, the second time 810 corresponds to the start time of the second UL transmission 406, and the third time 812 corresponds to the end time of the second UL transmission 406. Therefore, Figure 4 The second transmission period 408 is equal to the time between the second time 810 and the third time 812.

[0112] As illustrated, the UE may transmit the first N1 symbols of the first UL transmission 402 at power P1 before and until the start of the second UL transmission 406 (e.g., its duration is less than the first transmission period 404). Therefore, between the first time 808 and the second time 810, the first transmission power 802 is equal to P1. In one embodiment, the first DMRS is transmitted at or near the start of the first UL transmission 402 (e.g., preloaded near the start of the first N1 symbols).

[0113] During the second transmission period 408, the UE can transmit the second UL transmission 406 with power P2. Therefore, between the second time 810 and the third time 812, the second transmission power 804 is equal to P2. Because the second transmission period 408 begins at the second time 810 and ends at the third time 812, the second transmission power 804 is equal to zero between the first time 808 and the second time 810, and between the third time 812 and the fourth time 814.

[0114] During the first transmission period 404 between the second time 810 and the third time 812, the first transmission power 802 is equal to 0. Furthermore, during the first transmission period 404 between the third time 812 and the fourth time 814, the first transmission power 802 ≤ P. cmax，c1 .

[0115] The total power transfer 806 between the first time 808 and the second time 810 is equal to P1, the total power transfer 806 between the second time 810 and the third time 812 is equal to P2, and the total power transfer 806 between the third time 812 and the fourth time 814 is ≤ P1. cmax，c1 .

[0116] Figure 9 This is a schematic block diagram of yet another embodiment of the timing diagram 900 illustrating power settings. Timing diagram 900 illustrates... Figure 4 The first transmission power 902 of the first UL transmission 402 described herein is used for Figure 4 The second transmission power 904 of the second UL transmission 406 described herein, and the total transmission power 906 which is the sum of the first transmission power 902 and the second transmission power 904, are also described. Furthermore, timing diagram 900 illustrates a first time 908, a second time 910, a third time 912, and a fourth time 914. The first time 908 corresponds to the start time of the first UL transmission 402, and the fourth time 914 corresponds to the end time of the first UL transmission 402. Therefore, Figure 4 The first transmission period 404 is equal to the time between the first time 908 and the fourth time 914. Furthermore, the second time 910 corresponds to the start time of the second UL transmission 406, and the third time 912 corresponds to the end time of the second UL transmission 406. Therefore, Figure 4 The second transmission period 408 is equal to the time between the second time 910 and the third time 912.

[0117] As illustrated, the UE may transmit the first N1 symbols of the first UL transmission 402 at power P1 before and until the start of the second UL transmission 406 (e.g., its duration is less than the first transmission period 404). Therefore, between the first time 908 and the second time 910, the first transmission power 902 is equal to P1. In one embodiment, the first DMRS is transmitted at or near the start of the first UL transmission 402 (e.g., preloaded near the start of the first N1 symbols).

[0118] During the second transmission period 408, the UE can transmit the second UL transmission 406 with power P2. Therefore, between the second time 910 and the third time 912, the second transmission power 904 is equal to P2. Because the second transmission period 408 begins at the second time 910 and ends at the third time 912, the second transmission power 904 is equal to zero between the first time 908 and the second time 910, and between the third time 912 and the fourth time 914.

[0119] During the first transmission period 404 between the second time 910 and the fourth time 914, the first transmission power 902 is equal to Min{Max{0,P} CMAX,c1 -P2},P1}.

[0120] Between the first time 908 and the second time 910, the total power transfer 906 is equal to P1, and between the second time 910 and the fourth time 914, the total power transfer 906 is equal to Min{P1}. CMAX,c1 ,P1+P2}.

[0121] In one embodiment, for the purpose of PUSCH, PUCCH, and / or SRS power control in a multi-beam wireless network, the UE may maintain a set of the following path loss estimates: (a) path loss estimates for all or a subset of gNB beams corresponding to the actually transmitted SS blocks; (b) path loss estimates for all or a subset of active gNB beams used for PUSCH and / or SRS transmissions (e.g., gNB beams configured for current surveillance-CSI acquisition- and / or potential PUSCH scheduling). (c) Path loss estimates for all or a subset of alternative and / or candidate gNB beams (e.g., beams used for beam switching); (d) Path loss estimates for all or a subset of gNB beams corresponding to and / or associated with configured SRS resources for UL beam management procedures; (e) Path loss estimates for all or a subset of active gNB beams used for PUCCH transmissions, if different from PUSCH beams (e.g., robust transmissions for control information), including beams configured for beam failure detection procedures; and / or (f) Path loss estimates for all or a subset of configured gNB beams used for mobility, RRM, RLM, and / or BFR procedures. It is understood that the sets of the above path loss estimates may not be mutually exclusive and / or may have non-empty overlap.

[0122] In some embodiments, for systems with beam reporting and beam management procedures, the number of path loss estimates to be maintained may not exceed the number of transmitted SS blocks and the fraction, multiple, or offset of the reported beams. For example, if the UE reports up to four good and / or active beams to the gNB, the UE may maintain no more than eight path loss estimates (e.g., eight is a multiple of four) for some of the transmitted SS blocks, active CSI-RS beams, and / or candidate beams.

[0123] In various embodiments, the gNB may categorize the set of path loss estimates based on channels and / or signals that take power control into account. In one embodiment, the gNB and / or UE may configure the path loss options (a), (b), (c), and / or (f) described herein for PUSCH power control; the options (a), (b), (c), (d), and / or (f) described herein for SRS power control; and / or the options (a), (b), (c), (e), and / or (f) described herein for PUCCH power control.

[0124] In some embodiments, if a UE with CA capability is configured with multiple bandwidth portions having different parameter sets, the UE can be configured with different open-loop power control parameters (e.g., different target SINR P0 and fractional path loss compensation factor α and / or path loss reference signal) and / or different closed-loop power control loops.

[0125] In some embodiments, the first time a UE is configured and / or reconfigured with a bandwidth portion having a corresponding parameter set different from the bandwidth portion configured for the UE, a PHR may be triggered to notify the gNB of an updated estimate of interference and / or path loss of the channel associated with the configured and / or reconfigured bandwidth portion.

[0126] In various embodiments, if the UE is configured to operate in one cell (and perhaps in other configured cells), the UE may be configured with the following OL power control configurations for dynamic scheduling (e.g., target SINR P0 and / or fractional path loss compensation factor α): at least two different OL configurations for eMBB and URLLC services; at least two different OL configurations for the two uplinks of the SUL configuration; and / or up to N_max different OL configurations for different PUSCH beams, where N_max corresponds to the maximum number of good and / or active beams reported by the UE in the beam management procedure. It should be noted that the above examples do not take into account the effect of the time slot set, or assume that the effect of the time slot set is captured along with the OL-PC configuration allocation for the beam.

[0127] In some embodiments, a separate OL-PC configuration may be used for PRACH transmissions. Furthermore, in some embodiments, a separate OL-PC configuration may be used for unlicensed transmissions.

[0128] In various embodiments, the UE can have up to four active beams. Therefore, the UE can have at least 14+1+1=16 different OL-PC configurations.

[0129] In one embodiment, if a UE in a multi-beam wireless network is configured with multiple closed loops (e.g., two closed loops) for PUSCH power control, the selection of the closed loop configuration (e.g., first closed loop, second closed loop) may depend on the indication of the set of active gNB beams used for PUSCH transmissions to the UE (possibly a Supplemental Uplink (SUL) and / or timeslot set), but may not depend on other PUSCH transmission characteristics and / or attributes, such as license type, service type, traffic type, etc. In such an embodiment, all PUSCH transmissions operating with the same gNB beam can be configured with the same closed-loop power control, regardless of the license type, traffic type, service type, and / or other PUSCH transmission characteristics and / or attributes.

[0130] In some embodiments, if the UE is operating in a multi-beam wireless network, regardless of whether the PUCSCH transmission is configured with one or more (e.g., two) closed loops for power control, the step size δ_PUSCH and / or application time K_PUSCH for the TPC command can depend on the license type, service type, traffic type, and / or other PUSCH transmission characteristics and / or attributes. For example, URLLC (compared to eMBB) or unlicensed transmissions (compared to dynamically licensed transmissions) can have a larger step size δ_PUSCH and / or a shorter application time K_PUSCH for faster convergence of closed-loop power control.

[0131] In various embodiments, if a new gNB beam is added to the set of active gNB beams for the UE, and the gNB beam has similar spatial characteristics and / or QCL assumptions to the UE's existing active gNB beams, then the current accumulated state of closed-loop power control for the existing active gNB beams can be applied to the newly added beam. In such embodiments, the addition of a gNB beam may not be considered an RRC reconfiguration (e.g., a reconfiguration of TCI and / or other power control-related RRC parameters) and / or may not cause any reset of the closed-loop power control parameters.

[0132] In some embodiments, if a new gNB beam is added to the set of active gNB beams for the UE, and the gNB beam has significantly different spatial characteristics and / or QCL assumptions from all existing active gNB beams for the UE, the accumulation of closed-loop power control linked only to the new gNB beam (and all other gNB beams sharing the same closed-loop power control) can be reset, but no other closed loops are reset after this beam configuration and / or reconfiguration.

[0133] In one embodiment, if some spatial relationships in the TCI are updated and / or reconfigured, the accumulated state of the corresponding closed-loop power control process after the TCI update may be reset for all PUSCH, SRS, and / or PUCCH transmissions corresponding to the TCI update and / or reconfiguration, or it may inherit the current and / or the last accumulated state that existed before the TCI update and / or reconfiguration. In such an embodiment, the decision to reset the accumulated state may depend on the similarity and / or difference of the spatial relationships before and / or after the TCI update. Moreover, in such an embodiment, for any PUSCH, SRS, and / or PUCCH transmissions that do not correspond to or are not associated with the TCI update and / or reconfiguration, the accumulated state of the corresponding closed-loop power control process may not be reset after the TCI update and / or reconfiguration (e.g., the corresponding closed-loop power control process may be performed in the current state and / or the last state of the CL-PC process before the TCI update and / or reconfiguration).

[0134] In some embodiments, if the first set of spatially similar gNB beams (e.g., those corresponding to one panel of the TRP) has significantly different spatial characteristics and / or QCL assumptions than the second set of gNB beams (e.g., those corresponding to a second panel of the TRP), the UE's closed-loop power control configuration can be selected from one of two configurations: either the first set or the second set of gNB beams can correspond to different closed loops for power control; or, if the UE attempts to switch from communication using the first set of beams to communication using the second set of beams, the corresponding closed-loop configuration can reset its accumulation.

[0135] In various embodiments, if a multi-panel UE uses the UE beam of the UE panel to operate using the gNB beam, and the UE is configured to potentially cause the UE to exceed the maximum configured output power of the UE panel (e.g., P...), CMAX，c，b Upon receiving a positive TPC command, or when the UE is operating in power-limited mode, the UE can initiate a UE TX beam scan (e.g., a U3 UL beam manager) to determine if any other UE beams from any other UE panel exist that can operate with the same gNB beam but facilitate larger panels. CMAX,c,b In such an embodiment, if the UE finds any such UE TX beam, the UE can autonomously perform a UE TX beam handover that is transparent to the gNB.

[0136] In some embodiments, if the UE is configured with multiple power control parameter sets for PUSCH corresponding to the set of active gNB beams, service type and / or traffic type (e.g., eMBB and / or URLLC), license type (e.g., licensed, unlicensed, and / or RAR), and / or any other PUSCH attributes for potential PUSCH transmissions, and if the UE is configured with several SRS resources (or multiple SRS resource sets, each consisting of one or more gNB beams) acquired by the UL and / or DL ​​CSI of the active gNB beams for potential PUSCH transmissions, the configuration of the power control parameter set of the SRS resources can be bound to the configuration of the power control parameter set of the active PUSCH beams, but may not be bound to different service types, license types, etc. For example, the configuration of the power control parameter set of each SRS resource acquired by the UL and / or DL ​​CSI of the active gNB beam intended for PUSCH transmission can be bound to (e.g., follow, use the same value, use the same value plus the configured offset, etc.) the configuration of the power control parameter set for the corresponding active gNB PUSCH beam, and: (i) a fixed default set of PUSCH transmission features and / or attributes such as service type, license type, etc.; or (ii) a set of PUSCH transmission features and / or attributes, such as service type, license type, etc., that vary semi-statically based on previous UE scheduling history (e.g., based on the most frequently used UE PUSCH transmission features and / or attributes within a time interval). In some embodiments, if a higher-layer power control configuration for SRS resources acquired by the UL and / or DL ​​CSI for an active gNB PUSCH beam is bound to a higher-layer power control configuration for those gNB PUSCH beams, and if the UE is scheduled via a transmission of an SRS resource acquired by the UL and / or DL ​​CSI for an active gNB PUSCH beam (e.g., based on a low-overhead mechanism for activating and / or triggering SRS resources by indicating the activation of an SR resource set including all SRS resources acquired by the UL and / or DL ​​CSI), an SRS resource indicator SRI (or an indicator for the SRS resource set acquired by the UL and / or DL ​​CSI) can be shown to the UE, which can signal to the UE which SRS and / or PUSCH power control configuration to follow.

[0137] In one embodiment, if the UE capability report includes UL and / or DL ​​mismatch characteristics (e.g., the UE reports that it may not support beam correspondence for one or more of the following reasons: the UE sometimes and / or always uses a different TX panel than the RX; the UE has poor calibration, such as because there is a large phase shift between the RX and TX beams; the UE has limitations on the use of the TX beam, for example, all beams are possible for the RX, but due to EIRP-like limitations, the UE can only use certain beams for the TX; the UE's TX and RX beams have different beamwidths, such as the RX beams are narrower, but the TX beams are wider; the UE's TX and RX phase networks have different granularities, such as the RX using finer phase shifts, while the TX uses coarser phase shifts; and / or the UE's beamforming capabilities differ for the TX and RX, such as only a limited number of beams (or beam patterns) are available for the TX, but all of these beams (and beam patterns) and their linear combinations are available for the RX), then the UE can report the average UL and / or DL ​​mismatch offset for each gNB beam to the gNB. If optimal UE beam operation is achieved through procedures such as UL beam management, the average UL and / or DL ​​mismatch can be an estimated average power offset for the UE, caused by any and / or all of the aforementioned non-corresponding characteristics calculated for each gNB beam present in the UE. For example, the average UL and / or DL ​​mismatch offset can be based on a statistical analysis of the adhesion performance of the electronics, PA, RF, and / or antenna components, or on an empirical average of power variation measurements in the UE's electronics, PA, RF, and / or antenna components over a time interval. In some embodiments, if a set of power control parameters is configured for the UE, the gNB can consider gNB beam-specific average UL and / or DL ​​mismatch offsets. It is understood that merging average UL and / or DL ​​mismatch offsets can facilitate the gNB configuring a single gNB beam as a DL reference signal for beam-non-corresponding path loss estimation (e.g., in contrast to configuring multiple gNB beams as DL-RS for path loss estimation via uniform and / or weighted averaging), and any remaining errors and discrepancies may be small enough to be captured by the gNB TPC command with timely and rapid convergence.

[0138] In some embodiments, if multiple UEs are configured with the same set of active gNB beams for PUSCH transmission, or if multiple UEs can share a subset of gNB beams within the configured gNB beams for their PUSCH transmissions, the gNB can group the set and / or subset of gNB beams and can jointly attempt UL and / or DL ​​CSI acquisition for the set and / or subset of gNB beams for multiple UEs by jointly triggering and / or activating SRS resources corresponding to the set and / or subset of gNB PUSCH beams (e.g., based on low-overhead mechanisms for activating and / or triggering those SRS resources, such as by configuring and indicating a set of SRS resources that includes all SRS resources related to UL and / or DLCSI acquisition of the gNB PUSCH beams). In such embodiments, the gNB can use TPC-SRS-RNTI to configure group-common TPC commands as part of the DCI to multiple UEs to facilitate joint and / or low-overhead mechanisms for signaling power control adjustments for SRS resources.

[0139] In various embodiments, if the SRS resource set and / or group is associated with a set of gNB beams in the UL beam management procedure (e.g., for beam determination, switching, scanning, and / or refinement), and if the SRS resource set and / or group is configured for multiple UEs (e.g., for lower overhead operations of any of the following procedures: beam management, triggering, activation, and / or power control), the gNB can use TPC-SRS-RNTI to configure group-common TPC commands as part of the DCI to multiple UEs.

[0140] In some embodiments, if an SRS transmission is not tied to any PUSCH transmission (e.g., the SRS transmission is not intended for UL and / or DL ​​CSI acquisition for any active gNB beam to perform a potential PUSCH transmission), the gNB can configure the UE with an independent closed-loop power control or no closed-loop power control. In one example, if an SRS transmission is configured for SRS antenna switching and / or SRS carrier switching, a separate, independent closed loop can be configured for the SRS transmission in the absence of corresponding PUSCH and / or PUCCH transmissions. In another example, if an SRS resource set and / or group contains multiple periodic (same periodicity) SRS resources intended for UL beam management, the gNB can configure independent closed-loop power for the SRS resource set and / or group. In yet another example, if a first SRS resource set and / or group includes multiple aperiodic SRS resources for UL beam management, and if the aperiodic SRS resources are also associated with the same gNB beams (or a subset of those gNB beams larger than a certain threshold) as a second SRS resource set with periodic SRS resources, then closed-loop power control of the second SRS resource set and / or group can be configured for the first SRS resource set and / or group, and any accumulated states can be achieved. In yet another example, if the SRS resource set and / or group includes multiple aperiodic SRS resources corresponding to a set of gNB beams not associated with any other SRS resource set and / or group with periodic SRS resources (e.g., if the aperiodic SRS resources correspond to a new set of gNb beams as a new candidate not previously configured in the UL beam management procedure), then the gNB may not configure closed-loop power control for that SRS resource set (e.g., relying solely on open-loop power control).

[0151] In some embodiments, method 1000 includes transmitting a third portion of the first uplink transmission at a fourth transmission power during a third time period following the second time period, wherein the fourth transmission power is determined based on: the first transmission power, the second transmission power, the third transmission power; a power boost factor for the first uplink transmission, the second uplink transmission, or a combination thereof; a scaling factor for the first uplink transmission, the second uplink transmission, or a combination thereof; the maximum output power configured for the first serving cell; the total maximum output power configured; or some combinations thereof.

[0152] In some embodiments, in response to a difference between a fourth transmission power and a second total transmission power greater than a threshold, transmission of a third portion of the first uplink transmission includes a second demodulation reference signal. In various embodiments, method 1000 includes transmitting the third portion of the first uplink transmission at the second total transmission power and without transmitting the second demodulation reference signal, in response to a difference between the fourth transmission power and the second total transmission power being less than a threshold. In one embodiment, method 1000 includes stopping transmission of the third portion of the first uplink transmission in response to: the number of symbols in the third portion being less than a first threshold; the fourth transmission power being less than a second threshold; or a combination thereof.

[0155] In various embodiments, if the first symbol is transmitted with a second symbol via a second uplink, then power scaling of the first uplink transmitted first symbol, power boosting of the first symbol, stopping the transmission of the first symbol, puncturing the transmission of the first symbol, discarding the transmission of the first symbol, or some combination thereof, are applied to the entire length of the first symbol.

[0157] In some embodiments, the first priority of the content of the first uplink transmission is based on a predetermined priority rule for uplink transmission, which assigns higher priority to content containing uplink control information. In some embodiments, the first priority corresponds to the content of the first uplink transmission during a first time period, a second time period, and a third time period. In various embodiments, the first uplink transmission and the second uplink transmission are decoded based on an estimated received power change, power limiting information indicating whether the user equipment is power-limited, an estimated transmit power difference, or some combination thereof, and the estimated received power change, power limiting information, estimated transmit power difference, or some combination thereof are used to scale the log-likelihood ratio.

[0158] In one embodiment, the second uplink transmission occurs semi-persistently during the first transmission period, such that there are alternating time periods in which the first uplink transmission and the second uplink transmission overlap, and the transmission power used for the first uplink transmission alternates between a second transmission power when the first uplink transmission and the second uplink transmission overlap and a third transmission power when the first uplink transmission and the second uplink transmission do not overlap.
